Marine Fire Damper (MFD)

Product catalog summary

Overview: The Wozair Marine Fire Damper (MFD) is designed for long-life reliability, preventing fire, gas, and smoke spread through ventilation systems. It is constructed with stainless steel isolation seals and oil-impregnated bearings, ensuring integrity in bulkheads and decks. The damper is tested for smoke clearance at 300°C for 1 hour and holds Type Approval Certification for cellulosic fire conditions from A-0 to A-60.

Specifications: The MFD is available in various sizes, with a minimum of 150W x 150H x 200D mm and a maximum of 2500W x 2100H x 300D mm. It complies with IMO FTP Code Part 3 and offers leakage classes to EN1751 standards. The damper is suitable for explosive atmospheres, certified by ATEX/IECEx.

Materials and Construction: The casing and flanges are made from stainless steel 304L/316L, galvanized sheet steel, or carbon steel, with thicknesses ranging from 2.0 mm to 5.0 mm. Blades are constructed from stainless steel with a minimum thickness of 1.2 mm, and shafts are continuous solid stainless steel. Bearings are oil-impregnated sintered bronze, with options for low temperature and low leakage.

Mechanical and Control Options: Options include increased flange thickness, stainless steel bearings, and various transitions for ductwork fitting. Control options include manual, electric, or pneumatic actuators, with customization for closing time, ATEX zones, design temperature, and IP level.

Certification and Performance: The MFD is certified by DNV GL, ABS, Bureau Veritas, and others, with CE marking under EN15650. It meets USCG standards and has undergone Module B and D conformity assessments. Performance data indicates total pressure loss across the damper when blades are fully open.

Ordering and Weights: The document provides detailed ordering codes and weight matrices for different configurations, including additional weights for various actuator options.

Contact Information: Wozair has offices in the UK, USA, Singapore, and the Middle East, with contact details provided for each location.

Marine Fire Damper The stainless steel isolation seals, oil impregnated bearings and low leakage bearing assemblies prevent fire, gas and smoke spread through ventilation systems, maintaining the integrity of that division, bulkhead or deck. For smoke clearance, the damper has been tested at 300°C for 1 hour. Manufactured using modern CNC laser cutting and folding processes, with metal to metal blade tip and blade edge sealing arrangements to achieve exceptional performance without the aid of gasket materials. The MFD holds Type Approval Certification with a number of Class Administrations for...
